.SH NAME
rwho \- who is logged in on local machines
.SH SYNOPSIS
.LP
.nf
\fBrwho\fR [\fB-a\fR]
.fi

.SH DESCRIPTION
.LP
The \fBrwho\fR command produces output similar to \fBwho\fR(1), but for all
machines on your network.  If no report has been received from a machine for 5
minutes, \fBrwho\fR assumes the machine is down, and does not report users last
known to be logged into that machine.
.sp
.LP
If a user has not typed to the system for a minute or more, \fBrwho\fR reports
this idle time.  If a user has not typed to the system for an hour or more, the
user is omitted from the output of \fBrwho\fR unless the \fB-a\fR flag is
given.
.SH OPTIONS
.ne 2
.na
\fB\fB-a\fR\fR
.ad
.RS 6n
Report all users whether or not they have typed to the system in the past hour.

.SH NOTES
.LP
\fBrwho\fR does not work through gateways.
.sp
.LP
The directory \fB/var/spool/rwho\fR must exist on the host from which
\fBrwho\fR is run.
.sp
.LP
This service takes up progressively more network bandwidth as the number of
hosts on the local net increases. For large networks, the cost becomes
prohibitive.
.sp
.LP
The \fBrwho\fR service daemon, \fBin.rwhod\fR(8), must be enabled for this
command to return useful results.
